On both mac and linux I'm getting unexpected sha1 checksum when I try to install the latest development release on FiPy.
Are you using the beta firmware updater?

@wstallwood
It sounds like in your application OTA updates would be the easiest. With firmwares older than 1.7.2.b1 you can use the generated appimg.bin to do a OTA update, after that you just need to use the regular firmware bin file for OTA. Please checkout this example: https://docs.pycom.io/chapter/tutorials/all/ota.html
